This man is awesome. I mean, there is no way one could compare the courses on quantum mechanics I took in my university to this one.

Never could imagine the problem of HO was this beautiful. He is awesome.

"a few blackboards ago" 🤣 I love it!

[@alexanderlograsso1653]

LOL!

[@galdali10]

Never heard such a clear explanation in such a short time

[@zacharythatcher7328]

The only hard part for me to understand was why at 6 min the inner product of two functions had to be positive. It is important to remember that they are the same function and that doing their inner product gives you their magnitude, which is positive. Thinking of them as vectors, if you take the inner product of a vector with itself, of course you'll get a positive number.

Its just a property of hilbert spaces

[@陈方可]

Brilliant!

[@shashanks.k855]

This is just fukin amazing.

4:20 how do we know its equal to one?, but the other side must obey greater or equal than zero?

[@prayogaliong5395]

Because psi is normalised, so (psi,psi) is 1 by definition. An inner product of something with itself is always greater or equal to zero.

Thanks 🤍❤️

Great sir 👍

[@not_amanullah]

This is helpful ❤️🤍

IF you could find the ground state wavefunction of something like an nv center, then reconstruct it onto a distant nv center, would entanglement sustain ?
even after the nv center has been excited, would it not want to rest back to the ground state and the wavefunction ?
restoring the entanglement ?
